Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. So when a large amount of data is being processed, it is very easy to cause memory corruption using a Heap-Buffer-Overflow. As for the Use-After-Free, Thread3->Malloc->Thread1->Free's->Thread2-Re-uses-Free'd Memory. The PSRT has stated that this is not a security vulnerability due to the fact that the attacker must be able to run code, however in some situations, such as function as a service, this vulnerability can potentially be used by an attacker to violate a trust boundary, as such the DWF feels this issue deserves a CVE.

Two memory leak flaws were found in the Linux kernel's mwifiexpcieinitevtring() function. A local attacker, able to reload the kernel module or hotplug Marvell WiFi hardware using this driver, can cause a denial of service (memory consumption) by triggering mwifiexmappcimemory() failures.

A flaw was found in the alarmtimernsleep() function in kernel/time/alarmtimer.c in the Linux kernel. The ktimeaddsafe() function is not used and an integer overflow can happen causing an alarm not to fire or possibly a denial-of-service if using a large relative timeout.

A flaw was found in the kernels implementation of the bluetooth HIDP (Human Interface Device Protocol). A local attacker with access permissions to the bluetooth device can issue an IOCTL which will trigger the dohidpsockioctl function in net/bluetooth/hidp/sock.c.c. This function can potentially leak potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not correctly NULL terminated.

A vulnerability was found in basesockcreate in drivers/isdn/mISDN/socket.c in the AFISDN network module in the Linux kernel does not enforce CAPNETRAW, which means that unprivileged users can create a raw socket.

ax25create in net/ax25/afax25.c in the AFAX25 network module in the Linux kernel 3.16 through 5.3.2 does not enforce CAPNETRAW, which means that unprivileged users can create a raw socket, aka CID-0614e2b73768.

It was discovered that processcrash() in data/apport in Canonical's Apport crash reporting tool may create crash files with incorrect group ownership, possibly exposing crash information beyond expected or intended groups.

An information-leak flaw was found in the Linux kernel's pcan USB driver. When a device using this driver connects to the system, the stack information is leaked to the CAN bus, a controller area network for automobiles. The highest threat with this vulnerability is breach of data confidentiality.

A flaw was found in the Linux kernel. The generation of the device ID from the network RNG internal state is predictable. The highest threat from this vulnerability is to data confidentiality.

In Ubuntu, Subiquity version 24.04.4 could leak sensitive user credentials during crash reporting. Upon installation failure, if a user submitted a bug report to Launchpad, Subiquity could include certain user credentials, such as the user's plaintext Wi-Fi password, in the attached logs.

In Ubuntu, ubuntu-desktop-provision version 24.04.4 could leak sensitive user credentials during crash reporting. Upon installation failure, if a user submitted a bug report to Launchpad, ubuntu-desktop-provision could include the user's password hash in the attached logs.

An information leak vulnerability in rtnetlink subsystem in Linux kernel was found in "net/core/rtnetlink.c". The stack object "map" has a total size of 32 bytes. Its last 4 bytes are padding generated by compiler. These padding bytes are not initialized and sent out via nlaput().

Apache Commons HttpClient 3.x, as used in Amazon Flexible Payments Service (FPS) merchant Java SDK and other products, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

A flaw was found in the Serialization component of OpenJDK. A reference to an uninitialized class descriptor encountered during object stream deserialization could cause an unexpected exception to be raised when processing an untrusted serialized input.

A flaw was found in the Nashorn JavaScript engine in the Scripting component of OpenJDK. The state machine of the regular expression Parser did not correctly handle empty string nodes in certain cases, which could cause an unexpected exception to be raised when processing a specially crafted regular expression.

A flaw was found in the Nashorn JavaScript engine in the Scripting component of OpenJDK. Processing of the forward references prior to checking for regular expression syntax errors could cause an unexpected exception to be raised when processing a specially crafted regular expression.

A flaw was found in the Serialization component of OpenJDK. The invokeWriteObject() method of the ObjectStreamClass method failed to catch InstantiationError exception during object stream deserialization, which could cause an unexpected exception to be raised when processing an untrusted serialized input.

A flaw was found in the Security component of OpenJDK. It was discovered that the unmarshalKeyInfo() method of the DOMKeyInfoFactory class and the unmarshalXMLSignature() method of the DOMXMLSignatureFactory class could raise exceptions not declared as thrown by these methods when reading key info or XML signature data from XML input.

It was discovered that crypto provider implementations in the JCE component of OpenJDK for crypto algorithms such as AES or SHA did not perform array bounds checks. This could lead to out-of-bounds access if compiler intrinsics were used instead of the Java runtime implementations of the specific operations.

It was discovered that the AccessController class implementation in the Security component of OpenJDK failed, in certain cases, to consider the current context and correctly restrict privileges based on it. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

drivers/tty/ntty.c in the Linux kernel before 4.14.11 allows local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ.
